kind of obvious to say ig but correlation =/= causation. for ex: fiber, (the plant material in our diets that is undigestable by us, but is digestible by the healthy bacteria in our intestines) both leads to a healthy "gut microbiome" while having the side effect of making your poops bigger and softer, such that it is easier for your intestines to push it through your digestive system.
Still, in case anyone was wondering, you are supposed to be pooping, aka "having bowel movements" once every day 2-3 times every day. If you aren't that regular, you may need to eat more beans & grains and less processed foods & meats
Exactly what I've heard from our pediatrician when talking about baby pooping. When someone reaches a certain age anything between 3 days and 3 times a day is OK, as long as it looks as a normal poo
Normal frequency is between 3 per day to 3 per week, but normal doesn't necessarily mean healthy. Populations eating high enough fiber diets to reach that 2-3 times a day number have 1/50th the rate of heart disease, gallstones, and appendicitis, 1/25th the rate of diverticulitis, hemorrhoids, varicose veins, and hiatal hernia, and 1/10th the rate of colon cancer
